Your PC in the basement and WIFI two floors above, is probably going to perform poorly. Good luck.Powerline adapters are not in my budget currently, my dad had one previously but I can only find one of the Powerline adapter. I would like to know as my pc will be in the basement and the WiFi modem is 2 floors up. I would like to play games, like siege, destiny 2, for honor and other multilayer games
